Aspiro, a Norwegian company headquartered in the Swedish town of Malmo, was not immediately available for comment.

According to DN, Jay-Z’s lawyers have accused Tidal’s former owners, including Norwegian media group Schibsted, of overstating the number of paying customers and having embellished the accounts ahead of the sale, a charge they have denied.

At the end of June, the Wall Street Journal reported US group Apple was in talks with Tidal regarding a possible purchase, aimed at beefing up its own streaming service Apple Music.

Tidal soared in popularity early this year after Beyonce — Jay-Z’s wife — released her latest album “Lemonade” exclusively on the service, although it was also broadcast in a film version on HBO and quickly made available on iTunes.

Tidal, which had a mixed reception after its relaunch last year, has also heavily promoted exclusives, such as albums by Rihanna and Kanye West.
